What type of piping is commonly used for gas distribution in residential and commercial applications?

Polyethylene piping is commonly used for gas distribution in residential and commercial applications due to its unique properties that make it well-suited for this purpose. One of the key advantages of polyethylene is its flexibility, which allows for easier installation, especially in areas with varying terrain or when navigating around existing structures. Its resistance to corrosion and chemicals also ensures longevity and reliability in transporting natural gas without the risk of degradation over time.

Additionally, polyethylene can be produced in various diameters and lengths, making it adaptable to different installation needs. This type of piping is typically used for underground gas distribution since it is lightweight and can be joined using heat fusion methods, creating a strong and leak-resistant connection.

In contrast, while copper and steel are used in some gas piping applications, they have limitations such as susceptibility to corrosion (for steel) and higher costs (for copper). PVC, on the other hand, is generally not approved for gas distribution due to its low heat resistance and potential to emit harmful fumes if exposed to high temperatures, making polyethylene the preferred choice for safe and effective gas distribution.
